Working with Trent and the staff at Dave Mungenast was
Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.
Had the truck a few months and have had more compliments
Had the truck a few months and have had more compliments than any vehicle I’ve ever driven. Just a sharp vehicle inside and out. Love the 2.7 engine and the leather interior and all the space both front and back.

Great dealership
Neal Collins was a great salesman. We found the perfect auto with is help. We would recommend him as well as the auto dealership to everyone. Thanks Neal!
F-150 - what you expect in a truck
24000 miles Crew cab 4x4 - for me, the perfect match between comfort, styling, and utility. Truck has a soft bed cover that allows me to expose as much of the bed as I need. Easy to retract and close.

Extremely easy buying process
Been looking at used trucks for some time. Trenary in Troy had a vehicle that I was interested in. Contacted the dealer, asked if truck was still there and set up an appointment to come take a look. My salesman had the truck up front and ready for me when I arrived. The entire process (including finance) went very smooth and I appreciate that! Thanks again!
High Tech
Great vehicle. I was not used to not having a printed owner’s manual. But, with continued and diligent use of the onboard screen and its videos and owner’s manual has answered all questions and issues. Love this pickup.

A REPUTABLE CAR SALESMAN!
Ed Rapien has been our salesman for 15 years for Ford-Mercury products. He is very professional, sells the cars for a fair price, helps with backing up any problems we have had, & I actually feel he is an honest car salesman.My only complaints are that Ford is no longer making sedans or the Mercury brand. These are not Ed's fault, however. Thank heaven they kept him when dealership was sold from Price-Gnade to Trenary.
THE 14TH GEN FORD F 150 IS A HIT!!!
The power, of the smallest engine, the 2.7 V6, Twin Turbo, is excellent. My average gas mileage is near 22 mpg. I am using Sheetz 88 Octane fuel. The 2021 F 150, XL/STX, Super Cab, FX4, has been a decent truck so far! I had some issues with the optional POWER GENERATOR,..and apparently, it's now fixed!? I may get a truck camper put on the bed!? However, it can be either a good hauler, or towing vehicle! My unit has the optional towing package.

Dave Sinclair stands by their product.
We have purchased 6 cars or trucks from Dave Sinclair Ford or Lincoln. They have always treated us well during and after the sell. We tried to buy a Chevy EV Bolt this month but the service was so bad we choose to keep our Lincoln instead. If I had not moved to the east coast last year, I would continue to only buy from Dave Sinclair.

Fun, energetic, and timely are a few words that describe my truck buying experience. From sales with Mo, to finance with Stacey, they made it easy to find selections that suited my needs. I was in and out in a few hours not all day. I highly recommend Jim Butler, they live up to the hype.

Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.
